Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566056, here are decompositions:

13 + 31566043 = 31566056
37 + 31566019 = 31566056
43 + 31566013 = 31566056
103 + 31565953 = 31566056
127 + 31565929 = 31566056
139 + 31565917 = 31566056
619 + 31565437 = 31566056
673 + 31565383 = 31566056

Showing the first eight; more decompositions exist.
